DULUTH — A 32-year-old Duluth man has a mystery on his hands.

Tyler Scouton said he received a postcard last week that appears to be from the World War II era. The card is postmarked April 23, 1945, and pictures the USS Cuttlefish, a submarine training vessel.

The card was sent by a man at the U.S. Naval Training Center in Great Lakes, Ill., and is addressed to a woman who once lived at Scouton’s address. The real mystery: The card has a modern-day postage stamp on it.

Scouton is trying to figure out where the postcard has been for 68 years and who placed the new stamp on it and sent it.

Scouton said he wants to get the postcard to the families’ descendants.
